Hello Kevin,

I recently built android on Ubuntu 13.04 for arndale board.

acpica-tools was available and was installed without problem on 13.04. May be 10.04 is too old.

Regarding the cp error, I also faced this error. Then I build with pinned-manifest.xml and it succeeded.

Can you trying downloading the pinned-manifest.xml file from http://releases.linaro.org/<VERSION>/... and try the below command -

./linaro_android_build_cmds.sh -m pinned-manifest.xml

Thanks,

-Meraj
